  • The key of numerical simulation of the problems of shock impact on interface is capturing accurately the material interfaces. The position of material interfaces were captured by level set, the parameter of ghost points were defined by modified ghost fluid method, accordingly the problem of multi-interfaces was split into several the problems of signal material interface. Based on the methods mentioned above, the numerical simulation of the series problems of shock impact on material interface were presented, and the evolvement of material interfaces were given. It is found that the strength of shock wave and the shape of material interface have great effect to vortex, whether or not the interface reverse depends on the density of two materials.
